    Legos Offer Researchers a Big Picture of Nanoscale Science

    By Molika Ashford Posted on 8.26.2009 3 Comments

    Whoever thinks science isn't fun must have never heard of Legos. The colorful construction toy has been used before as a cellular teaching tool. But these days, even researchers working in the nanoscale world get to play around a little.

    Video: Taser Tests New Tri-Fire X3 On Their Own Employees

    By John Mahoney Posted on 7.15.2009 34 Comments

    Taser has been breathlessly fanning the hype flames for their newest "less lethal" weapon, the X3. Now, they've sent us the first video of it in action, striking three unlucky Taser staffers who (I can only assume) volunteered for the inglorious task of being guinea pigs.

    When I wrote my comment above, I was not necessarily implying that tasers should not be used by police at all. As DXN3585 just said, the real issue is that many police officers who use tasers do not appreciate the risks associated with their use. I believe that videos such as this one released by the taser company mislead the public about the safety of their product. There is a big difference in the health risks associated with tasing a calm, healthy individual once during a demonstration, vs. tasing an agitated disoriented individual repeatedly until he stops moving (Robert Dziekański incident).

    seatellite, Maybe you are a bit misinformed, Here's some info for you reading: en.wikipedia.org/wiki/Robert_Dzieka%C5%84ski_Taser_incident Video here (graphic content): www.cbc.ca/mrl3/8752/bc/ondemand/video/YVRTASERVIDEO.wmv This incident was a pretty big deal here in Canada, I think it's made a lot of people think twice about tazers and their use.

    Thar She Blows

    By Gregory Mone Posted on 1.12.2009 10 Comments

    When Kai Grundt announced his decision to build the ultimate snowblower from a discarded V8 engine, a friend of his just laughed. So a year later, instead of showing his buddy the finished product, Grundt showed him what it could do. He buried the man's truck under a seven-foot-tall pyramid of snow. From two houses away.

    GM Vice Chairman Calls Global Warming A "Total Crock of S**t"

    Heres an odd PR move making the blog rounds today: Bob Lutz, the General Motors Vice Chairman whos driving the charge to build the Chevy Volt plug-in hybrid, was recently quoted in D Magazine calling global warming a crock of s**t.

    Sigh.... I'm really disappointed by the ignorance that people have about climate change. No wonder our governments aren't doing anything to help, the voting public does not understand the issue. I've put down my thoughts in the comments section of "Climate Change—Don’t Blame It on the Sun"... I won't bother to post again here.

    Climate Change—Don’t Blame It on the Sun

    By Posted on 2.16.2008 21 Comments

    AAAS 2008, Boston, MA Sallie Baliunas, an astrophysicist at the Harvard Smithsonian Center for Astrophysics, is pointing to a slide called Interdecadal Magnetic Variability Berillium 10. Its supposed to communicate something about the relationship between the suns intensity and climate change. All I see is a collection of squiggly lines. It could be an EKG or a seismograph test. The man sitting next to me appears to be equally lost. Hes snoring. The woman next to him is staring at her shoelaces.

    Also, the IPCC definitely considers the affect of H2O in the atmosphere: Warmer climate = more water vapor in the atmosphere, leads to greater warming More water vapor= more clouds, leads to cooling. I believe this was covered in great detail in the last report.

    CO2 has such a greater affect than H2O because of the relative concentrations. H2O and CO2 absorb at certain wavelengths. Since the atmosphere is already saturated with H2O, it is already absorbing all it can at that particular wavelength. Since there is much less CO2, an increase in CO2 means the atmosphere will absorb more efficiently at that particular wavelength. For the same reason, CH4 and N2O have a greater warming potential than CO2. As for warming on Mars and Titan.... I assure you we know much more about our own planet...

    So I just noticed another comment you made and it made me think of something else: "They contend that most scientists believe this junk when in fact, most do not." This reminds me of one of my biggest peeves..... just because someone is a scientist, doesn't mean that they are an expert on climate change. For example, I could be a biologist, but that doesn't give me authority to be an expert on climatology or atmospheric science. Again, that's what the peer review process is for. Before you can publish something, you're work needs to be "approved" by fellow scientists who are experts in that particular field. It always irks me when I see something along the lines of "Dr. So and So from somewhere USA, states that climate change is a hoax". You look at his(or her) credentials and see that this Dr. is actually a PhD in Computer Science, or Economics or something else completely unrelated to atmospheric or climate science.

    So, first I check out Phil Valentine on wikipedia, I had never heard of him. And he's a conservative radio talk show host in Tennessee. Great. I'm sure he's an expert on this subject area then :) Anyways.... ok first link.... Temperature monitors report widescale global cooling http://www.dailytech.com/Temperature+Monitors+Report+Worldwide+Global+Cooling/article10866.htm Ok, so he's using anecdotal evidence of cold weather this year to support the idea that the planet is actually cooling, rather than warming. Well, anecdotal evidence is a terrible indicator of a long term trend. Also, he says that NASA and others have data indicate that this year was cooler on average than previous years. Fair enough. But one cool year is not an indication of a long term climate change. That's why scientists are typically looking at 10, 30 and 50 year trends. Global weather is sort of like the stock market..... it's always going up and down. Since you don't like the IPCC (I'll address that later...) here's a peer reviewed article to support this: Antarctic atmospheric temperature trend patterns from satellite observations Johanson CM (Johanson, Celeste M.), Fu Q (Fu, Qiang) GEOPHYSICAL RESEARCH LETTERS Volume: 34 Issue: 12 Article Number: L12703 Published: JUN 19 2007 I have access to it through my academic institution, you may have trouble getting access to it though, or you might need to pay, I'm not sure. A bit further down the page: Study finds natural cause for rapid Arctic warming http://www.dailytech.com/Study+Finds+Natural+Cause+for+Rapid+Arctic+Warming/article10216.htm So wow.... someone would read this and think that these scientists have found a natural explanation for global warming.... ok, lets take a look at the original research: Vertical structure of recent Arctic warming published in Nature, you can read the abstract here: http://www.nature.com/nature/journal/v451/n7174/pdf/nature06502.pdf So first of all, if my research actually debunked the current understanding of global warming, I sure would have put that into the title! If you read the abstract, really what this article is about is that these researchers measured the vertical structure of the warming trend of arctic temperatures. They found at higher altitudes, the atmosphere is actually warming up faster than at the ground surface. The arctic is currently warming much faster than people expected. One of the possible explanations is that as sea ice and snow melts, the changing albedo allows the earth surface to absorb more radiation, and increase in temperature. The higher temperature increases at high altitudes indicates that instead, it is likely related to atmospheric circulation. Therefore, if you read the original article, you can see that this research had absolutely nothing to do with finding a "natural cause" for global warming. They are conducting new research into some of the feedback mechanisms that causes certain parts of the globe to heat up faster than others. See here's the thing. Greenhouse gases (especially CO2) are the major cause of warming. You can't deny that the concentration of these gases are increasing. You can check out the raw data here: http://agage.eas.gatech.edu/index.htm The climate forcing attributed to increasing concentrations of greenhouse gases is dead easy to calculate. CO2 for example will absorb infra-red radiation at a very specific wavelength. This can be measured in the lab. We know what wavelengths the earth emits (blackbody radiation). Then it can easily be calculated. Ignoring all other factors, the increasing concentrations of these gases will lead to global warming (or more accurately climate change, since some areas actually cool in response to changing atmospheric and oceanic circulations patterns). Climate forcing attributed to greenhouse gases far outweighs the forcing attributed to other factors. Where is this CO2 (and other gases) coming from. Well, again, it's easy to calculate using a simple mass balance approach. We know how much we are producing, and how much is produced naturally, and how much is absorbed naturally. It's also easy to prove this by measuring the isotopic composition of atmospheric CO2. Again, since you don't like the IPCC, here's another article (again you might have trouble tracking it down): Anthropogenic emissions of CO2 and CH4 in an urban environment Kuc T, Rozanski K, Zimnoch M, Necki JM, Korus A APPLIED ENERGY Volume: 75 Issue: 3-4 Pages: 193-203 Published: JUL-AUG 2003 As for the IPCC... I think they are doing a great job of communicating the science to the policymakers. The job of scientists is to determine the truth and then communicate it to the public and to the governments. It fine to debate about what should be done or what shouldn't be done in response to climate change, but it's counterproductive to pretend that there is a debate in the scientific community when this really isn't the case. As far as the IPCC reports are concerned.... if anything, they actually represent a very conservative estimate of the risks/causes of climate change. Since the IPCC committees are drawing from published scientific literature to write these reports, they always lag a couple years behind the most recent data. Also, the IPCC scientists are under a lot of pressure not to overstate the climate change issues, because, although they are not a political entity, they do face political pressure to be more "industry friendly". Also, the reports risk being dismissed if they are too alarmist. You can read more about the IPCC on the wikipedia entry, and make your own decision. http://en.wikipedia.org/wiki/Intergovernmental_Panel_on_Climate_Change Since wikipedia is open to public editing, you could argue that it is not too biased. But to summarize, you need to base your arguments on actual peer reviewed articles. The peer review process is what ensures that scientific research is valid and bias free. I like to refer to the IPCC because they draw from peer reviewed research, and they are experts in the field as well.

    auferret, sorry I haven't gotten back to you yet, I haven't been on this site in a while. It's late, and I haven't had a chance to check out that link in much detail. One caution though... take time to look at the original source. One article in your link there was a editorial about a blog, about a paper originally published in the peer reviewed journal "Nature". The problem with this is that it is like a game of "telephone", the original message gets distorted along the way. I'll try to look at this again tomorrow.
